Professeur Sorbonne Université : Jean-Michel RAIMOND & Directeur : Michel BRUNE

The team, headed by J.M. Raimond and M. Brune, focuses on quantum explorations with Rydberg atoms. These long-lived, very excited states are strongly coupled to static and millimeter-wave fields and experience a huge mutual dipole-dipole interaction. The team exploits these properties for Cavity Quantum Electrodynamics experiments, where one atom interacts with a few photons in a high Q cavity. It realizes quantum-enabled measurements of electric and magnetic fields based on quantum superposition of Rydberg states reminiscent of the famous Schrödinger cat. It also aims at the realization of a spin-array quantum simulator based on interacting, laser-trapped ‘circular’ Rydberg atoms.
